CAMP COOKSTQVE.

Application filed March 14, 1927. Serial N 0. 175,124.

This invention relates to camp cook stoves. Objects of this invention are to provide a novel form of camp cook stove or portable folding stove which is so constructed that the gasoline or fuel tank-together with the projecting parts may be detached and readily stored within the body of the stove, and which may be readily coupled to the burner when it is desired to operate the stove without requiring a sliding fittingor threading of the projecting tube through an aperture or into a socket, but instead, in which a butt joint is employed and is held tight inherently by the construction of the apparatus, the weight of the tank holding the butt joint tight. 7 g V Further objects are to provide a simple form of stove which may be readily 0011-" structed and which is adapted to furnish two or more burners with selective control, whereby one or more of the burners may be used at a time, Y

An embodiment of the invention is'shown in the accompanying drawings in which:

Figure 1 is a plan view of the stove with parts broken awayshowing the cover open;

Figure 2 is a. view partly in section showing the device in elevation; I

Figure 3 is a transverse sectional view showing the tankin stored position;

Figure 1 is an enlarged detail of the butt joint, suchview being partly in section;

Figure 5 is a sectional view approximately on the line 55 of Figure 1.

,Referring to the drawings, it will be seen that the stove comprises a box-like metal housing or body portion 1 within which the parts are placed. Thisbody portion is provided with inwardly turned lugs or flanges 2 adapted to receive amovable or. detachable grate of any suitable 7 construction, such grate, however, being omitted for the sake of clearness. The body portion is also provided with a hingedly mounted sheet metal top 3 whichlis adapted to beopened out when the ,stove'i s iniuse or to be closed to completely house the mechanism. .Any suit able fastening meansma-y'be providedfor the. cover, such means, however, being omittedas they may be of the conventional yp 1 7 1t The body portion carries a burner which is rigidly attached and which consists, of an upwardly and longitudinally curving mixing tube 4t which opens downwardly into a v manifold ordistributor pipe 5, such pipe leading upwardly to the main burner 6 and" an auxiliary burner 7. The main burner remains 1n communication with the manifold or supply pipe '5 for the combustible mixture, whereas the auxiliary burner 7 may be out off from the manifold 5 by means of a gate valve consisting of a disc-like member 8 pivotally mounted upon the burner, as indicated at 9. 1 This disc-like valve is proylded .with an aperture 10 adapted to reg- 1ster with the aperture opening into the burner when the partsare in the position shown in Figure 1. In order to manipulate this valve, an outwardly projecting lever 11 is formed, preferably integrally with the valve 8 and projects outwardly through the casing, such lever being provided with an upturned thumb-piece or manipulating portion 12. In order to protect the rock lever 11 from blows which would tend to distort it, the body of the casing 1 is bowed outwardly, as indicated at 13 along the arc of a circle, as most clearly. shown in Figure 1, and a'slot is provided through which the lever 11. projects. Thus, the manipulating portion of the lever is at all times in close relation to the bodyof the casing and can not therefore be readily distorted.

The burner structure is provided with an entrance opening 14 (see Figure 4) into whichthe gas is forced as it passes through. the needle valve opening 15, such opening being controlled by a needle valve .16 carried by a valve rod 17. It is adjusted inthe usual manner by means of a hand wheel 18, as shown in Figures 1 and 2. The air passes upwardly through the open bottom, downwardly projecting portion 19 of the burner structure. A heating cup 20 is formedintegrally with the burner structure, as shown in Figures 4 and 5, and is adaptedtoreceive some of the liquid fuel to initially heat the generator tube 21. 7 It is to be noted particu- 'larly that the generator tube 21 terminates in an abrupt shoulder or flange 22- for a purpose hereinafter to, appear. The other end of the generator tube communicates with the rank through the medium of the supply tube 23" which extends downwardly into i The shoulder or'fiange 22 of the generator tube has itsflat face directly contacting with a flat machined face 23 formed on the front end of the mixing tube at of theburner. The

flat faces of the shoulder 2'2 and of the burner mixing tube -l: thus constitute a. hutt joint. The means for holding this butt joint tightly closed consists of a slightly springy hooleshaped clip 24; secured in any suitable manner as by means of screws. for instance, to the burner tube. This hook-shaped clip is provided with the upwardly extending hooked portion (see Figure 4:) which engages over the top edge of the flange 22 of the mixing tube. The lower portion of the flange 22 of such tube cont-acts at two spaced points, as indicated at 25, with the sides of the heating cup, as most clearly shown in Figure 5. Thus, a three-point contact is provided for the flange 22 and it is securely held against displacement.

it is to be noted particularly fron'i Figures 2 and t, that the heating cup is of elongated rectangular construction. This mode of :liorming the parts facilitates the positioning of the generator tuhe and its flange 22, as

shown in dotted and full lines in Figure l.

and as will be described in greater detail hereinafter.

The fuel tank 26 (see Figure 2) is adapted to be supported b means of a pair of curved spaced arms 27 'l'ormed of strap metal and preferably braced by means of the member 28. These arms are hineged, as indicated at 29, to the end of the body portion 11. of the store, as shown in Figure 2, and when not holding; the tank are adapted to be swung inwardly into the dotted line position shown in Figure 2. liurther, the tank, as stated previously, is adapted to he stored within the hotly portion, particularly as shown in Figure 2. \Vhen so stored. the tank 26 rests upon the bottom of the body portion 1. and its manipulating hand wheel 18 bears against an inwardly turned portion .lll oi the body of the store. The other end. namely. the flange 92, rests upon a. small shell ill formed l a bracing mci'nber 82 located within the store.

In using the device. the fuel tank is lifted from within the housing or compartment 1, and is held with its generator tube and flange in the dotted line position shown in Figure l. Some fuel is allowed to Flow into the heating cup and thereafter the upper edge of the flange is hooked oeneath clip 2d and the parts are rocked into the full line position shown in Figure i. and also shown in Figures 1 and it. is to he noted that the body portion is provided with an open topped notch 33 in its end wall into which the mixing tuhe 2i rocks. The outwardly rocked arms 22 of the frame supportthe fuel tank, as shown in Figure 2. This downward rocking of the parts causes the flange 22 to rock about its upper edge beneath the clip and to ride upon the marginal or side edges of the heating cup, thus tightly forcingitself against the flat face 23 of the burner structure and maintaining the tight butt joint, previously discussed.

In this connection, it is to he noted that the center part of the l'lange 22 sligl'itly cut out, as indicated at Ell: in Figure t, so as to protect the point of the needle valve from inadvertent contact with any object during positioning; and removal of the parts. It is to he noted also that a slight or shallow air nular groove 35 is formed in the flat face of the flange 22 of the mixing tube.

It will be seen that a novel form of camp store has been provided in which no threading of the generator tube through apertures and into sockets is required, hut instead, in which a butt joint is employed inherently held tight by the weight oi? the fuel tank.

llurthcr, it will be seen that; the device so made that the fuel tank may be freely rocked into operative position and that the generator tube is freely received within an open topped notch in the end wall of the casing.

It will be seen further that no skill or care is required on the part of the operator in a-seniblinp; the parts as accurate fits are not required. (lhviously, it the hinge 22 is slightly displaced laterally, it will correctly position itself, as shown in .lFigure 5, due to its three point support.

it is to he distinctly understood that the term camp store is intended to cover not only the stores used solely for camping, but other collapsible or portable stores of this general type.

Although the inventioi'i has been described in considerable detail, such doscrii'ition is intended as illust atire rather than lin'iitinpj as the invention may he variously embodied. and as the scope of such invention is to bc (lOlOl'll'llllOtl as claimed.
